Yeah, just mark it and relieve it with a mill or file or grinder. No big deal. S/F....Ken M

The Mancini rockers are Harland Sharp bodies without the roller bearings, I've heard nothing but good things about them. They seem the best value for dollar, and you don't need a lot for a flat tappet, but the stock rockers aren't adequate. If you can find the Erson/Crane/Mopar ductile iron...

That much lift on what's probably an aggressive cam is going to murder those rocker arms. Spring pressures? There will be a lot of flex, and a pushrod will eventually poke through the rocker arm. S/F....Ken M

Sleeve it. S/F....Ken M

Did they talk about turning it into a B-spec crank? Mains to 2.625 and rods to 2.200. If you're just going to use it for a doorstop, and it's a factory 3.75 forged crank, I'd be willing to buy it and see if I can repurpose it to a low deck. S/F....Ken M

The Icon piston is a better choice, if you want to swing the $200'ish difference in price just for the better 1/16" ring package. In a perfect world I'd prefer if it had a .990 pin, but that piston was designed by a guy on moparts for class racing, and they use stock rods, no bushings, from...

Icon 687 is the best choice, agree with above. S/F....Ken M

Even if it's used up past 440 dimensions, it can be ground for a low deck and BBC rods and serve a long time further. S/F....Ken M

B1's are wedge heads, the Predators are a canted valve setup and some classes don't allow/penalize them. There really isn't anything comparable from Indy, maybe the 600-13's, but I have no experience with those. The B1 Originals are commonly ported to over 400cfm, the moved centerline heads...

That seems like it's down a cylinder, what do the plugs look like? Were there air/fuel ratios recorded? I did a 406" B block with mildly rubbed on 452 heads that flowed 245cfm@.5, 8.2:1 compression, Erson 230 something hydraulic roller, with an out of the box Holley 750 vacuum secondary on a...

I'm posting this as another option, and some data: I built a 400 using the stock crank, albeit forged, and had the rod journals ground to 2.200 (BBC) used 6.800 rods with the Icon IC828 piston with a compression height of 1.485. The block was decked to 9.965, so the pistons were .010 proud...

We just put 8 sleeves in a megablock because it wouldn't go 4.500. If you know everything else is good, sleeve away. S/F....Ken M

You guys are creating stress risers in aluminum parts for nothing. And MIGing on heat treated wrist pins.....FFS. S/F....Ken M

If you want nice mopar heads that legitimately flow 400cfm plus, you need to be looking at B-1's, not Indy stuff, at least not anything less than 600's or Predator stuff. S/F....Ken M

Sleeves are stronger than the block material. When you sleeve, it's part of a complete rebuild, you re-hone every hole to spec, unless it's some desperate "I need this cause I ain't got no money" 3rd world nonsense. It's so much cheaper to do it right the first time, instead of blowing...

If they clear the guides and oil seals with the ID, sure. Use some sort of locator to protect the soft aluminum from the springs eating them up. S/F....Ken M

I'll take it, please let me know total shipped to 60016. S/F....Ken M

A 470 would be nicer simply from easier rod bearing access, but IME, rod bearings were never a big deal for BBM, it's always finding decent low deck main bearings that's hard. More cubes is usually better, but I thought you had pistons? If (quality) crank grinding is not expensive, as it is...

Girdles primary task is to prevent the caps/fasteners from "flag-poling", which contributes to fretting. Think of it as a vibration issue. Aluminum caps help due to their vibration absorption properties. Since conventional wedge blocks are not reinforced at the cross bolt locations like hemi...

Icon IC687 piston. Look at that one. S/F....Ken M

Erson E419115. 230/238 on a 112 LSA. 114 would be even better, less overlap is better for your interests. S/F....Ken M

Studs and aluminum caps are default SOP with my engines, but I'd be concerned with which bearing died? #4? If a good pan and external reservoir isn't enough, I'd be looking to go to dry sump. Switching to low deck would have been good also, but if you're already building that's kinda late to...

As the picture shows, what I mean is the metal smeared around by dull tooling and excessive feed rates. On aftermarket cranks, this isn't an issue. S/F...Ken M

Torque is almost a pure function of displacement, NA, as said. Buy the largest stroker you can get if you want torque. A 4.25 or 4.5inch crank in the 440 block with a cleaned up set of factory heads, good exhaust valves, HR or hydraulic flat tappet cam and you should be happy, except at the...

If you can contour the front and rear of the counterweights and remove flashing and sharp edges on your lathe, I would like to see a video:-) S/F....Ken M

Yes, I've got two, as well as one 4.5" crank cut to 2.625" Check the overall counterweight diameter, but otherwise no issues. The BBM rod journal size doesn't clear the oil pickup IME, might have just been the rods I was using. S/F....Ken M

A good carb can hang with EFI on a dyno, for a given build. That's it. Where EFI leaves it in the dust all day, everyday, is living with the thing and designing the build. Dry ports are huge difference. Spot on mixture, all the time, huge difference. Modern engines have tiny ring...

Run whatever heads need less work. The 452's are supposedly easier to port, the sets I've done are not that hard to get to 265-275cfm @ 600. S/F...Ken M

I have a slightly used 500 inch stroker kit for a RB block. I just balanced it three weeks ago. It was orphaned at a shop, which closed and sat in a hydraulic repair shop for years until I made the guy an offer on it. The story I got, and the parts make this seem possible, is that it was...

^ I've seen good things about them, also Morel. Lunati are Morel, and are quite reasonably priced. S/F...Ken M
